People often try not to think about the worst case scenario and negative events, instead consoling themselves with the thought “that will never happen to me.” However, businesses can’t afford to take the risk of not planning for disasters, especially where their data is concerned. An increased reliance on computer networks, databases and services has made businesses more vulnerable in the event of a network outage.
You may have heard people mention the subject of Disaster Recovery (DRaaS) recently, especially DR in the cloud, which is becoming an increasingly popular topic within the IT industry. What exactly is that though and how does it work?
Disaster Recovery is essentially a business’ insurance policy that gets it back on its feet quickly in the case of unforeseen damage to where its data is stored.
Disaster Recovery came about in the late 70s due to a realisation that computers and data centres were becoming increasingly important to how organisations operated. Often systems could be down for several days when things went wrong, so developing a plan to ensure faster recovery became a priority. Traditionally, DR has been a part of a company’s Business Continuity (BC) Program, focusing on IT and technology systems that businesses depend upon, such as networking, data, hardware and infrastructure.
Traditional disaster recovery services replicate the application state between two data centres, so a backup site could take over and activate a new replica of the applicationusing the most recently copied data. Nowadays though, if your applications are already running in a virtualised environment, then cloud-based disaster recovery can be a viable alternative. Disaster Recovery as a Service (DRaaS) is a cloud-based way to replicate infrastructure, applications and data for full system recovery. Replicating to the cloud is a relatively simple way to ensure data can be restored in the event of disaster.
As stated above, every business needs to have a contingency plan in place in the event of a disaster. This is known as a business continuity plan which should include information on what employees need to do after a disaster, how your business will remain in operation and the best way to restore data. Your DR plan will be a critical part of this. A cloud DR plan will also include Recovery Point Objectives (RPOs) and Recovery Time Objectives (RTOs). As every business will differ in the applications that it runs, there is no single plan for DR in the cloud. Therefore, a cloud DR plan will be distinctive and unique to each organisation.
Creating a DR plan begins with the process of categorising applications, services and data by level of importance, based upon the amount of disruption that can be afforded before it negatively impacts the business. RTOs will then determine the approach taken to DR. The most important aspect of this process is identifying all crucial applications and data that need to be included in your plan and leaving out irrelevant data or applications. This can help centre a DR plan, controlling costs and making it easier to test occasionally.
